* Terminology:
* AHUB: Audio Hub; a cross-bar switch between the audio devices: DMA FIFOs,
* I2S controllers, SPDIF controllers, and DAMs.
* XBAR: The core cross-bar component of the AHUB.
* CIF: Client Interface; the HW module connecting an audio device to the
* XBAR.
* DAM: Digital Audio Mixer: A HW module that mixes multiple audio streams,
* possibly including sample-rate conversion.
*
* Each TX CIF transmits data into the XBAR. Each RX CIF can receive audio
* transmitted by a particular TX CIF.
*
* This driver is currently very simplistic; many HW features are not
* exposed; DAMs are not supported, only 16-bit stereo audio is supported,
* etc.
